1.1. Credentials and Access

1.1.1. SSH Access

  • Please use your GEANT AD account(GEANT\dante.xxx or GEANT\Firsname.Lastname)to have ssh access and sudoer rights on the required servers.

1.1.2. Other Access

  • Required credentials are in the "GÉANT Dashboard v3" LastPass folder

1.2. Problems

1.2.1. New alarms are not appearing in the gui

1.2.1.1. Possible Cause: Traps not being processed by RabbitMQ

1.2.1.1.1. Analysis
  1. Open one or more of the following RabbitMQ management consoles.  (Credentials are in the "GÉANT Dashboard v3" LastPass folder)
  2. Scroll down to the "Nodes" section
  3. There should be 3 rows in the table and all status icons should be green (currently - there is a red bar showing a deprecated node - this will be removed when possible).  The expected node names are:
    • rabbit@prod-noc-alarms01
    • rabbit@prod-noc-alarms02
    • rabbit@prod-noc-alarms03
1.2.1.1.2. Solution
  1. If one of the 3 nodes is failing or missing from the list, log into the failing server via ssh and restart the RabbitMQ service: 
    • systemctl restart dashboard-docker.service
  2. After a minute or two the management consoles should show the cluster is restored.
1.2.1.1.3. Solution #2
  1. If all 3 nodes appear in the list, but if the state of the nodes is different when logging into their respective administration gui's

1.2.2. Collectors have stopped working

1.2.2.1. Analysis

  1. Open this Correlation status dashboard
  2. Scroll down to the "Collectors" panel
  3. Check that the graph shows a nonzero rate of traps being processes

1.2.2.2. Solution

  1. On each of the following servers:
    • net-alarms01.geant.org
    • net-alarms02.geant.org
    • net-alarms03.geant.org
  2. Log in via ssh and execute the following command: 
    • sudo systemctl restart trap_collector

1.2.3. Possible Cause: Correlators have stopped working

1.2.3.1. Analysis

  1. Open this Correlation status dashboard
  2. Scroll down to the "Collectors" panel
  3. Check that the graph shows the leader collector processing a non-zero rate of traps.  The current leader can be identified by the FORWARDER with state 2 in the "Raft States" panel.

1.2.3.2. Solution

  1. On each of the following servers:
    • net-alarms01.geant.org
    • net-alarms02.geant.org
    • net-alarms03.geant.org
  2. Log in via ssh and execute the following command: 
    • sudo systemctl restart trap_correlator
